What is Profit Margin?
Profit margin measures how much of your revenue becomes actual profit after accounting for costs. It's expressed as a percentage, making it easy to compare profitability across time periods, products, and businesses.
There are two primary types of profit margin:
For example, if you generate $100,000 in revenue with $40,000 in COGS and $35,000 in operating expenses, your gross margin is 60% and your net margin is 25%.
Gross Margin vs Net Margin: What's the Difference?
Gross Profit Margin
Gross margin measures profitability after direct costs of producing/acquiring products. It tells you how efficiently you're sourcing and pricing products.
- Includes: Revenue minus product cost, shipping, packaging
- Shows: Product-level profitability
- Used for: Pricing decisions, product mix optimization
Net Profit Margin
Net margin measures profitability after ALL costs, including operating expenses. It shows how much of every dollar actually becomes profit.
- Includes: All costs including marketing, salaries, rent, software
- Shows: Overall business profitability
- Used for: Business valuation, investor analysis, strategic planning

Strategies to Improve Profit Margins
Improve Gross Margin
- Negotiate with suppliers: Volume discounts, better payment terms
- Optimize shipping: Better carrier rates, packaging efficiency
- Raise prices: Test price increases on strong products
- Focus on high-margin products: Shift product mix toward better margins
Improve Net Margin
- Reduce CAC: Improve conversion rates and targeting efficiency
- Automate operations: Reduce labor costs through automation
- Audit software costs: Eliminate unused tools and consolidate platforms
- Increase AOV: Higher order values spread fixed costs more efficiently
Increase Volume Efficiently
Fixed costs become a smaller percentage of revenue as you grow. Focus on scaling profitable channels while keeping CAC in check. Each additional dollar of revenue with stable costs improves net margin.
Common Profit Margin Mistakes
Ignoring Hidden Costs
Many businesses underestimate COGS by forgetting shipping to customers, packaging materials, transaction fees, and returns. Include all costs that scale with orders.
Confusing Revenue with Profit
Growing revenue while margins decline is a path to failure. A business doing $1M at 5% margin is often less healthy than one doing $500K at 20% margin.
Racing to the Bottom on Price
Competing primarily on price destroys margins. Focus on differentiation, customer experience, and value instead of always being the cheapest option.
Not Tracking by Product
Overall margins can mask unprofitable products. Track margins by product or category to identify which items are actually making money.
Frequently Asked Questions
A healthy eCommerce business typically has 40-60% gross margin and 5-15% net margin. These vary significantly by industry: beauty products often have 60-80% gross margins, while electronics may only achieve 15-35%. Focus on your specific industry benchmarks rather than general averages.
COGS includes all direct costs to acquire and deliver products: product purchase price, inbound shipping/freight, import duties, packaging materials, and outbound shipping to customers. It does not include marketing, salaries, rent, or software costs, which are operating expenses.
Improve gross margin by negotiating better supplier pricing (especially at volume), optimizing packaging to reduce material and shipping costs, raising prices where the market allows, focusing your product mix on higher-margin items, and reducing returns through better product descriptions and quality control.
Net margin accounts for all operating expenses including marketing, salaries, rent, software, and other overhead. It's normal for net margin to be significantly lower than gross margin. If the gap is too wide, audit operating expenses for optimization opportunities, especially in marketing efficiency and software consolidation.
Absolutely. Overall margins can mask poorly performing products. Some products may have negative margins after accounting for returns and marketing costs. Product-level margin analysis helps you identify what to promote, what to discontinue, and where to focus pricing optimization.
